VALVE-BAG.

Specification of Letters Patent.

Application filed Febnuary 2, 1903. Seria1 No.-141,550.

To all whom it may concern:

Be it known that I, ADELMER M BATEs, a citizen of the United States, residing at Clevelandyin the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Valve-Bags, of

Figure 1 is a side view of the bag blank; Fig. 2 is a corresponding view of the same with an extension valve piece rojecting therefrom or attached thereto; Fig. 3 is a view of the bag blank of Fig. 1 folded down the necessary distance and stitched so as to U form a long inwardly extending valve; Fig.'

4 is a like view of a bag with a similar valve formed from the bag blank of Fig. '2; Fig. 5 is a detail view, with parts broken away, to show the inwardly extending valve of the devices of Figs. 2 and 4,- Fig. 6 is a detail cross section on the line 6-6, Fi 5.

Like parts are indicated by the same letter in all the figures.

A A are the sides of'the bag.

B B are extension pieces formed integral with or preferably attached to the side portionsof the bag. j

C indicates the turned'down corner of the bag blank, which is associated with the valve extenslon D is the seam which is formed along the edgeD of the extension piece and the edge l) of the bag blank, when they are folded together as shown in Fig. 4. Thus, obviously, a valve opening is rovided which passesthrough the cornero the bag blank and between the two sides of the extension piece B.

E is the turned down corner portion of the bag of Fig. 3 and F the seam through the same.

G is the projecting unused portion of the bag blank and J that portion of the bag blank corresponding to the extension piece 11% to form the inwardly projecting valve of These several drawings are intended simply to diagrammaticallyillustrate my invention and not to indicate that it cannot be applied except as here shown. 1

My invention is made use of to provide. relatively long and narrow valve and to'do this with little or no waste of goods. If'We' desire to have a valve the depth-of which,'--

measured in the direction leading toward the,

inside of the ba is substantially greater than the diagona yarranged valve-opening;-

do this by'extending the--- we must obviously valve inwardly. This can be'accomplished'" as indicated in Fig. 3, where however there would be entirely useless.-

'65 is a great waste of material, for the' part G By attaching to the ba thevalve exten= sion piece B, which may e either sewed or gummed to the body of the bag, or which might of course be formed integral with the body of the bag, we get all the benefits and obviate all the difficulties of the other devices. When the extensions are turned down and brought into the proper position,

as indicated in Fig. 4, we have a long extension valve, but it is composed entirely of the extension piece. This extension iece may of course beof any desired materia and may be made ofscrap and waste. It is desirable of course in all such bags to have uniformity and symmetry. The uniformity of size,

shape and construction of the valve is imf portant because the bags are filled by machinery, and symmetry is important both to make the goods sell readily andalso for ease and convenience in packing, shipping and handling. By means of theextension device here illustrated, these several objects are all accom lished. When the extension piece is folded over, its edges are brought 1nto alinement with thee ges of the bag body, and when this is done,

obviously, if the extension pieces are all of the same size, the

valves produced will always be in the same relative position and of the same relative size. These features of construction herein referred to are not so important in small bags, but they become important in large bags and the also become important in the case of sma bags when they are made of certain materials. shown any depth of valve can be obt'amed and the extension may be of such length as to proceed nearly to the other edge or side of the bag, if that be desired. The extenslon which I have here shown is intended preferably for use in connection with cloth or sim- By the system here any kind of bag.
